Reference:
WTW Engineers are responsible for the technical development and the design of Auto Tracking Antennas, which were delivered in the last 17 years to customers all over the world.

That are well-known customers in the aviation and aerospace industry in Europe, USA, Asia and South Africa.
WTW Engineers developed and designed small portable Antennas, and customized mobile and stationary Antennas with up to 6.3 m Diameter (example 6.3m Antenna DLR Neustrelitz, see Picture ebove) for other companies .

March 2015feed_wtw_antenna
In cooperation with our customer WTW Engineers improved the G/T of an existing 6,3m Antenna at DLR Neustrelitz from 17,68dB/°K to 19,05dB/°K (S-Band) by developing a complete new L/S-Band Cross-Dipol. A part of that work was the Installation of new RF cabling, dry air supply for the antenna feed and a new cavity filter for another frequency.

August 2020
As part of functional adjustments and improvements to the system performance, the new WTW GUI including a new main computer on the ACE / DSCOVR antenna in Neustrelitz was put into operation in August 2020.
Among other things, functional expansions such as the fully integrated sun tracking are included in the new WTW GUI. The GUI was developed in close coordination with the customer and according to his wishes. In addition, absolute encoders with a 26-bit resolution were installed in both axes, making reference runs superfluous after reinitializing the antenna system.
